SPECIFICATION forming part of Letters Patent No. 279,461, dated June 12,1883.i

' Application filed April e, 1583. (Nummer.)

` To all whom t may concern:

will enable others skilled in the art to which it pertains to make anduse the same.

My invention relates to improvements in devices for applyinganti-friction rollers tojournal-boxes, but more especially to applyingsaid rollers tocar-axle boxes, although one part of the device maybeapplied to road-wagons; and it consists in certain features ofconstruction and combination `of parts, as will hereinafter bedescribed, and pointed out in the claims.

In the drawings, Figure l is an end view of a car-axle box, showing alsoan end view of a car-axle and anti-friction rollers. Fig.2 is a top viewof the box. Figs. 3 and 4 are sectional views of a car-axle and box,showing also portions of my new device. Fig. 5 shows a part of my devicewhen applied to axle-bearings where the wheel revolves on the axle, asin road-.wagons A represents a box with an arm extending on either side,each provided with a seat for a spring, as at A. rIhe 'holes at c arefor attaching braces. The central portion of the box is bored out toreceive the axle B, surrounded by the anti-friction rollers a. Theserollers are each pivoted at each end, as at a', in rings,as shown at c.These rings hold the rollers in their respective relative positions toeach other. ,f

To the sides of the box A are bolted the dang-es C, as shown in Figs. 3and lvl, These flanges do not touch the journal, but hold the rollers inposition cndwise. The box A is kept in position endwise on the journalby collars on each side of it,as shown at D, d, D, and d, Fig. 3. Thecollars D and D are attached' to the axle, and have their respectivecollars (l and d attached to them by loose-iitting dowclpins,as at di.The collars D and D are grooved on their faces next their respectiveattached collars, and these grooves are provided with rings of elasticpacking, preferably of rubber,

weai ot' parts, and saving also all annoyancev that when compressed willallow the respective collars to come together, but will also con# tinueto form a tight joint, keeping out dust and retaining the Oil in the boxwhen the co1- lars are slightly apart, and will also keep the collars dand d.' against their respective flanges C and C. The side grooves maybe made in any shape that is desired; but I prefer the semicircularforni, as shown at d. The collar D may be attached to theV axle in anysuitable manner, or may be; formed by the hub of the car-wheel. Ineither case the collar D is screwed Onto the axle just far enough toleave the movable partsI free to turn,and at the same time having aslittle room for end-play ofthe parts as possible. The joints between thecol lars d and d and their respective flanges C and C 'should vbe groundj oints., It will be seen that by this adjustment of parts the rollersuv are free from all labor endwise.

Vhen it is not desired to have the axle extend through the outside ofthe box, an arrangement of parts may be had as shown in Fig.4,where theiiange C is used,entirely clos ing the end of the box. In this cascthecollar b is substituted in place of the collar Din Fig. 3, and isscrewed onto the axle, holding the flange C in place on the axle andpreventing undue longitudinal movement oithe box. The box, rollers, andthe flange C are then placed in position and held together by the boltsc.

In Fig.5 is shown `the application of the collars D, d, D', and d asapplied to axles oi'ordinary road-wagons. In thiskind ofvehicles thejoints orbearings between the ends of thehub and the collars orshoulders on the axle vare usually packed with leather. This packing isAsoon worn by the accumulation ot' dust between the parts, and causesmuch annoyance by the parts rattling, and a-lso by the free discharge ofgrease at both ends of the hub. p 3y the application of these collarshereinbefore described the inner collars are, by the elasticity of thesaid rubber packing, kept in close contact with the ends of the hub,thereby exclud- 1e dust, and consequently reducing the from grease andfrom theirattling ofthe parts. Owing to the small size ofthecollarspvhen ap- IOO plied to road-Wagons, it may be advisable not togroove them,but to use the rubber,asshown in Fig. 5 at d".

l. A journal axle-box having a suitable bore for receiving an axle, andarms extending from the upper and lower edges of its sides,whichterminate in conjoined portions, provided with seats for springs andholes for attaching the box to the other parts of i the truck,substantially as shown and described.

2. `In a solid boX providedwith anti-frietion rollers and provided withthe iianges C and C, the eonibination,with the adjustable collars D, d,D', and d', of the respective elastic packing rings di and d, formingwith their respective collars an extension-joint, keeping the innercollars, d and d, against their respective flanges, and also keeping outthe dust and retaining the oil in the box,substantially as described,and for the purpose specified.

3. The eo1nbination,\vith the coll ars D, d, D', and d and theirrespective dowel-pins di', of

the elastic packing-rings d, making an eXpansion-joint and keeping thecollars cl and d against their respective lateral bearing, therebykeeping out the dust from between the parts and preventing the escape ofoil and grease, and also preventing the rattling of the parts7substantially as and for the purpose set forth.

In testimony whereof I signthis speciiieation, in the presence of twowitnesses,this 28th
